This unfortunately introduces a lot of overhead and doesn't scale well for larger applications. WebGL calls are already incredibly slow compared to native, and the trampolining between WASM and JS world adds on top.

When WASM got released (around 2017), there was already that discussion to allow direct bindings without a JS roundtrip, but AFAIK there is still no actual implementation for this in any browser.

AssemblyScript initially targeted TS->WASM compilation, by only supporting a strict subset of the TS language. But at some point they dropped that idea and defined their own TS-like language. I don't know the reason for this, but my guess is that TS is too dynamic to just directly compile it to WASM?

For example reverse engineering and parsing binary file formats

There is a WebKit based HTML renderer called Ultralight. It works by creating hooks and intercepting the rendering calls of WebKit in order to allow embedding it easily.

Unfortunately the license of Ultralight is questionable, and it's not open-source either by bypassing the WebKit license (which is very questionable as well since WebKit itself is BSD-licensed).

Having such a project as a free open-source variant would be a huge game changer in my opinion.

Hey thanks for you comment.

The Ray-Tracing Extension is currently only available for Windows and Linux.

My next plan is to implement the extension into Dawn's D3D12 backend, so I can build chromium with my Dawn fork and have Ray-Tracing available directly in the browser (at least for myself) :)
